Rapid shear of initially anisotropic turbulence in a rotating frame

摘要: In the present study, we investigate, using inviscid rapid distortion theory, evolution of sheared turbulence in a rotating frame as function rotation rate (including stable, transitional, and unstable regimes), examine sensitivity results for various nonisotropic initial conditions. Analytical solutions are derived stresses structure dimensionality tensor components three one-dimensional two-dimensional initializations. From these solutions, calculate asymptotic states turbulence, which compared to exact numerical solution three-dimensional initially isotropic case. investigation it is shown that qualitative characteristics regime represented quite accurately when dependent at least on axis frame. For transitional stable regimes, though, dependence on...
